We just got back and I was about to post this as my best tip from our trip. We had a couple of bigger souvenirs... a droid from Droid Depot and a Figment popcorn bucket among other things. It was clear my son was going to struggle getting through the airport, especially with the droid since the handle on the cardboard box digs in to your hand!! The morning we were checking out of the Swan, I bought two medium reusable bags for $1.50 each. They were perfect for our purposes - just the right size for the droid and figment (I actually think we could have fit everything in one large bag but they were out), had a shoulder strap and made life much easier getting through the airport. Plus they are cute and a nice, cheap souvenir! They are still the 50th anniversary. They are not out on display and you do need to ask for them - very glad I did.
